In a recent study, researchers with the US National Oceanic and Atmospheric Administration (NOAA) analyzed more than 30,000 instances of by-catch recorded by 95 fisheries between 2010 and 2015. The scientists assessed how each of the fisheries—which included the relatively modest California halibut trawl fishery, the mid-Atlantic lobster pot fishery, and the Bering Sea/Aleutian Islands pollock trawl fishery, one of the largest fisheries in the world—performed in terms of by-catch.
